Culligan FM-100-C Faucet Mount Water Filter Reviews

This is an efficient water filter that uses activated carbon fiber to filter out contaminants and make water safe for consumption.

It removes foul odors such as chlorine, improves the taste of tap water and eliminates harmful pollutants such as lead, light sediment and particulate class 1.

The Culligan FM-100’s filter cartridge is easily replaceable and can last up to 2 months. This is approximately 200 gallons of clean, healthy water at a flow rate of 0.5 gallons per minute.

The filter has a light indicator that will flash red when it needs to be replaced. This is powered by a battery and is a convenient reminder beforehand.

It uses a 55/64-27 female metal collar and 15/16-27 male adapter that fits most aerator faucets. It is compact in design and easy to install with no tools required.

Simply pull on the diverter tab to automatically switch from filtered to unfiltered water.
